    Stuffed with 800-fill hydrophobic DriDown™, the Sierra Designs BTU -20 sleeping bag features a DriZone™ waterproof, breathable membrane for comfort in the coldest, wettest environments.

    • Down is widely considered the best insulation available, but when wet it quickly loses loft and the ability to keep you warm; DriDown is treated to resist moisture
    • Proprietary process treats each individual goose down plume with a molecular-level polymer so the down stays dry longer, lofts better and dries faster than untreated down
    • DriDown insulation stays dry 10 times longer, retains 170% more loft when exposed to moisture and dries 33% faster than untreated down
    • DriZone waterproof, breathable fabric allows moisture to escape while keeping rain out; 30-denier polyester lining fabric is comfortable next to skin
    • Baffle construction keeps down from migrating, eliminating cold spots
    • 40 in. zipper keeps weight down and won't let out all the warmth when you're getting in and out of the sleeping bag; locking slider is backed by wide, antisnag binding tape
    • Snag-free zipper tracks prevent the dreaded stuck zipper by creating a barrier between the lining and the zipper track
    • Fully insulated draft tube backing the zipper keeps body heat in and cold air out
    • Ergonomic, nonrestrictive hood cradles your head in warmth; use the drawcords to cinch the hood snug around your head
    • Includes an internal media pocket for your cell phone or alarm clock
    • Sierra Designs BTU -20 comes with stuff sack and storage bag

    Imported.
